Chronic atrophic gastritis generally develops from chronic non-atrophic gastritis, and the most likely cause may be Helicobacter pylori infection. Of course, there are also other reasons, such as poor dietary habits, emotional factors, etc. In such cases, it is first necessary to check for Helicobacter pylori infection, usually using a breath test. If Helicobacter pylori infection is present, quadruple therapy is generally used for eradication treatment. Eradication of Helicobacter pylori can be very helpful for patients with atrophic gastritis, and in some cases, can partially reverse the atrophy. If there is no Helicobacter pylori infection, symptomatic treatment is generally the main approach. Additionally, conditioning through traditional Chinese medicine can also be very helpful. (Specific medication use should be carried out under the guidance of a doctor.)
